Launched in 2014, Galvan made it a mission to offer up a new kind of occasion wear - think clean, pared-back and ultra-elegant. The Sienna slip dress is made in a shimmering material that gently cascades down the body like water, while its midi silhouette allows you to show off your favourite pair of heels. Notice the tie fastening at the back - its the perfect focal point to complete such a beautiful piece.
